The ACUPWR Papers

Using 100-Volt Roland Music Equipment Outside of Japan

What happens when you find an old, analog synthesizer at a yard sale for a steal of a price and you get it home only to find that it takes 100 volts of AC and your wall outlet is delivering 120? Cue the “wah wah” trombones?   Not quite. Older Music equipment manufactured by Japanese companies (such as Roland, Yamaha, and Korg) for sale in Japan always have a power requirement of 100 volts, since the AC power over there is 100 volts. [Note that these older keyboards do not use an external power supply that can handle 100-250-volt AC power, as is the case with most newer electronic devices.] Does this mean you’re plum out of luck trying to...

ACUPWR featured in Harmonycentral.com

ACUPWR is proud beyond belief harmonycentral.com, the premier website and forum for musicians, music enthusiasts, home recording geeks, and anyone and everyone involved in music and sound, has hosted an article written by ACUPWR’s Mike Bieber titled, Transformers, Not the Movie: “When touring in a land of unfamiliar voltages, make sure you choose the right kind of transformer.” The article addresses international voltage conversion as it relates to touring musicians. The article can be found at harmonycentral.com/articles/transformers-for-touring-musicians. We’ve blogged before about ACUPWR being the safest and most reliable transformer for musicians relocating or touring overseas with “fixed-voltage” amps or instruments (see our blog article Shut Up and Play Yer Guitar in Denmark. By fixed-voltage, we’re referring to equipment with a...

ACUPWR and Vitamix: A Voltage Cornucopia Made in Food Heaven

You bought an American-made Vitamix blender because you’re serious about whole food nutrition and eating healthy. And if you’ve invested in a Vitamix product over a lower-priced competitor, you’ve also invested in your overall well being and longevity—definitely money well spent.     Not surprising, you’ll find Vitamix machines used the world over. Foodies, followers of the health and fitness lifestyle, restaurateurs, commercial enterprises or ordinary individuals—whomever you are and whatever you do, Vitamix products are sought after for multitude reasons that have everything to do with made-in-USA quality and reputation, and all the great attributes of Vitamix.   It’s needless to say that Vitamix products are sought after here and internationally. But with regard to the latter, they’re considerably...

ACUPWR Tru-Watts™ Power = No Two-Times (2x) the Wattage!

The reason ACUPWR voltage transformers kick you-know-what over our competition has everything to do with the overload protection circuit in nearly all of our transformers. This circuit which uses a thermal protection sensor to determine overheating (caused by voltage surge or excessive wattage) and then shut the unit off until it cools down, whereupon it will automatically restart and function as if nothing happened. Because of our thermal protection sensor, an ACUPWR transformer will function normally at 20-percent beyond its stated wattage. At 50-percent beyond stated wattage, an ACUPWR transformer will work for about an hour before auto shutdown takes place. One thing you can never expect from ACUPWR transformers is a fire. That’s because our transformer products will function...

Read This If You’re Relocating Internationally with a Refrigerator, Freezer, Wine Cooler, Washer/Dryer and Any Appliance with a High-Power Motor. Then, Buy an ACUPWR AUC or ADC Transformer!

If you’re relocating overseas with an appliance that uses a high-power motor, READ THIS FIRST!   Items such as refrigerators, freezers, large wine coolers, washers, dryers, and big air conditioners, to name a few examples, rely on larger high-power motors to get the job done. Nonetheless, those kinds of appliances won’t work efficiently by only converting voltage with a basic step-up or step-down transformer from ACUPWR. This is because high-power motors are affected by the AC line frequency—an often overlooked player when it comes to household electricity.   We’ve blogged about line frequency in the past and to recap here, line frequency is the number of cycles per second electricity alternates between positive and negative polarity as it moves from...
